The LCS Yirrell was a Union-class DropShip in service to the Lyran Commonwealth. In 2853 it was part of the transport flotilla that brought relief forces to Hesperus II, after the LCS Invincible had smashed through the Draconis Combine siege in what became known as the sixth, seventh and eight battles for Hesperus II. On 10 November 2853 the relief fleet including the Yirrell battled a Draconis Combine blockade flotilla in close orbit over Hesperus II, and emerged victorious.[1]
